Abstract (en)
[origin: WO2006000429A1] The invention relates to a melt spinning device for a plurality of multifilament yarns and to a method for spreading a plurality of multifilament yarns in said melt spinning device. The melt spinning device used for producing multifilament yarns comprises a plurality of spinning nozzles for extruding a plurality of filament bundles, a preparation device for separately combining the filament bundles to individual yarns and a plurality of treatment devices. The filament bundles, when being extruded, are guided with a center distance and the yarns in the treatment device with a substantially smaller treatment distance. The aim of the invention is to provide an especially compact melt spinning device and to allow a rapid and uncomplicated threading of the filament bundles. For this purpose, a spreading aid comprising a plurality of separating yarn guides is mounted downstream of the preparation device in the thread path. The separating yarn guides are arranged at a yarn distance to each other which is substantially smaller than the center distance between the spinning nozzles. The filament bundles can thus be immediately separated by the movement of a manually guided suction device which withdraws the filament bundles directly from the spinning nozzles during spreading.
